THE EVENT ANALYSIS OF SYSTEMIC TEAMWORK (EAST): METHODOLOGY AND ANALYSES OF RAILWAY MAINTENANCE TASKS

摘要

EAST (Event Analysis for Systemic Teamwork) is an analysis methodology which combines seven human factors techniques in order to investigate command, control, communications, computers and intelligence (C4i) (Harris & White, 1987). The methodology has been developed by the DTC HFI. This paper focuses on two methods used in EAST, the critical decision method (CDM) and prepositional networks. This paper describes the application of the methods to C4i activities for railway track maintenance.
